No I did not test two drivers. I installed Xrite software, and try to create color profile with Argyll software. First I recognize device working with original driver in Argyll. But after I measure patches, which I measured with ColorMunki and Argyll, I got different result. With I1pro2 something is wrong with some of colors (for example some blue and turquoise). Also with highlight and shadows. With I1pro2 shadows are very good but light colors almost disappear, and gray shades are not correct. With Colormunki all was ok (not perfect quality), but shadows never was really good. So question is: Did I got wrong readings because of driver or something else?
